XAxisField issue on "ROC Chart" widget

[iguerra]

I'm using ROC Chard widget

it works fine, linking an infotable to "Data" and selecting the XAxisField and DataField 1..2....

However the XAsixField can be parametrized.

If i link XAsixField to a string (eg a textbox, just to try) giving the name of the field to use, the widget does not works.

I can make it running only if a select directly on the widget the infotable field use.

Has anyone used this XAsixField as a parameter ?

Is there a particular "syntax" for selecting the field name with XAsixField ?

Just to be sure are you referring to the Chart widget from the Marketplace?

[iguerra]

probably it was installed by thingworx analytics (Analytics Builder)

I didn't take from marketplace.

This seems to be the only widget allowing a Line X-Y  chart and possibility to dynamically customize the axis fields.
